IMPROVEMENT IN LANTERNS.

Specification forming part of Letters Patent No. 35,835, dated July 8,1862.

To @ZZ whom, it. may concern.- Beit known that I, LUKE C. OBER, of Bos'ton, in the county of Suffolk and State of Mas sachusetts, have inventeda new and useful Improvement in Lanterns whose lamps are intended toproduce light by the inflammation of kerosene or other hydrocarbonliquid rich in carbon; and I do hereby declare the same to he fullydescribed in the following specificaY tion,and illustrated in theaccompanying drawings, of whicht Figure 1 denotes au elevation, and Fig.2 a longitudinal section, of my improved lantern.

In carrying out my invention I dispense with the ordinary chimney, andso construct the glass casing as to serve both as a chimney and as aeasing to the lantern.

The nature of my invention consists in the arrangement ofan india-rubberpacking between the detlector supporter and casing, whereby a tightconnection is formed, so as to prevent any currents of air from passingupward between the said supporter and easing, such currents being causedto iow into the deflector and pass upward through and around it, ashereinafter set forth.

In the drawings, A denotes the lamp, and B the glass lantern-case.

O denotes the lower metallic portion of the lantern, whose sides areformed foraminous.

The lamp is such as is in coalition use .for burning coal-oil-that is,it is vprovided with a wick-tube, D, wick E, and wick-elevator F, aforaminons deflector-supporter, G, anda defiector, H. On the upperportion of the de- Ileotoresupporter I form awide annular ilange, a,which I extend horizontally, and cover the same with indiav rubber orother suitable elastic material, d.

The object of making` the packing or cont nection elastic is to maintaina perfectly tight joint under any expansion ofthe metallic supporter, aswell as to prevent any breakage of the glass portion by an expansion ofthe metallic portion.

The glass casing of the lantern is affixed to the eap`g,wliich is unitedto the lower portion ofthe lantern in the ordinary manner. 'Moreover,the said casing, near its lower part, is formed with a contraction orneck, b, the part c, or that portion intended to rest upon the packingd, being formed flaring, as seen in the drawings. Such part c, when inplace resting upon the indiarubber packing, servers to prevent thecurrents ot' air from passing up around the outer edges of thesupporter, whereby al1 the air passing upward is concentrated and madeto pass into the detlector, the greater portion passing upward throughthe same, while a smaller nportion escapes through the orifices formedtransversely through the lower part of the deflector and Hows upwardaround the external surface thereof, whereby the dame is properlysupplied with oxygen.

fff, &c., denote metallic wires or guardbars having their lower endsfastened in the screw-cap g, while their upper ends are affixed iuametallic cap or ange, I, extending around and supporting the upper,part of the glass casing B. K is a conical guard or heat-deflector,which serves to del-lect the heat of the lamp from the hand of a person,while L is the handle or bail, which is attached to the metallic cap I,as seen in the drawings.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1S-

The arrangement of india-rubber or other elastic packing between thedeilector -supporter and the glass casing of the lantern, whereby thecurrents of air are prevented from passing up between the said supporterand
